Indoor and outdoor seamless positioning system based on Android device and positioning method thereof

Abstract

The invention discloses an indoor and outdoor seamless positioning system based on an Android device, comprising: an outdoor positioning unit, an indoor positioning unit, a background detection unit and a function configuration unit; the outdoor positioning unit includes: an outdoor electronic map and a GPS module; To obtain the latitude and longitude coordinates of the current location, after correction and conversion into encrypted latitude and longitude data displayed on the outdoor electronic map; the background detection part includes: the floor detection module and the environment detection module; the floor detection module obtains the altitude of the current location in real time; the environment detection module It is used to detect the environment of the current location in real time; the indoor positioning part is used for indoor space positioning, and the positioning result is displayed on the indoor electronic map; the function configuration part is used to establish and view the WIFI fingerprint database. The present invention integrates GPS positioning and WIFI fingerprint positioning and combines indoor and outdoor environment detection and floor detection to realize true seamless positioning. The invention has good universality, low cost and high positioning accuracy.

Description

technical field [0001] The invention relates to the field of positioning technology and location service technology, in particular to an Android-based indoor and outdoor seamless positioning system and method integrating GPS, WIFI positioning technology and multi-sensor fusion. Background technique [0002] With the rapid development of information technology, the demand for location-based services is increasing, and people's desire to obtain location information anytime and anywhere is becoming more and more intense. [0003] At present, global satellite navigation and positioning systems such as GPS, GLONASS and Beidou positioning and navigation are becoming more and more mature, and have been successfully used in military, industrial, commercial and other fields. However, due to the limitations of satellite positioning technology itself, the above-mentioned global satellite navigation and positioning system cannot be directly transplanted into indoor scenes, and is blocke...

AI Technical Summary

Problems solved by technology

However, due to the limitations of satellite positioning technology itself, the above-mentioned global satellite navigation and positioning system cannot be directly transplanted into indoor scenes, and is blocked by walls, buildings, etc., and GPS and other signals are so attenuated that it is impossible to locate indoors, so people began to explore indoor scenes. Under the current positioning technology, Bluetooth, WIFI, ultrasonic, infrared, RFID, Zigbee and other positioning technologies have emerged and are experiencing a period of vigorous development.
